Kinetic and structural understanding of bulk and supported vanadium-based catalysts for furfural oxidation to maleic anhydride
The kinetics of gas-phase furfural partial oxidation to maleic anhydride (MA) was studied over bulk vanadium-phosphorus-based catalysts obtained by aqueous (VPAq) and organic (VPOr) methods and compared to a supported V 2 O 5 /Al 2 O 3 catalyst. The solids were characterized by N 2 adsorption-desorp...
